Legacy pass that translates LLVM IR into MachineInstr for GlobalISel.
Synopsis
Declared in <llvm/CodeGen/GlobalISel/IRTranslator.h>
class IRTranslatorLegacy
: public MachineFunctionPassDescription
Technically the pass should run on an hypothetical MachineModule, since it should translate Global into some sort of MachineGlobal. The MachineGlobal should ultimately just be a transfer of ownership of the interesting bits that are relevant to represent a global value. That being said, we could investigate what would it cost to just duplicate the information from the LLVM IR. The idea is that ultimately we would be able to free up the memory used by the LLVM IR as soon as the translation is over.
